| description:
|
In 2011 the Alaska Congressional Delegation requested federal support in modernizing Alaska map data. Collection of a 5-meter resolution elevation grid for Alaska began in 2012, replacing the former 60-meter statewide elevation grid. Radar technology called IfSAR (Interferometric Synthetic Aperture Radar) is used to collect the data because it can penetrate the clouds, smoke and haze that are often present in Alaska. The data are free to the public for any use. Alaska IfSAR acquisition supports the broader national 3D Elevation Program. |
